Anyone ever have these spots on outdoor plants?

Hey guys. I've checked around the forums, but haven't been able to figure out what these spots are. They're circular and appear to have rings, similar to a tree. They dry out as they get bigger and eventually become cripsy to the touch. My plant is in a 10 gallon pot about 3 weeks into flowering.

I hear what your saying about mold, but its the actual leaf itself that's turning that color, not something on the leaf. I think if left alone the dead tissue will mold.

My grow room is the great outdoors, so there's not much I can do about humidity.

Looks like a burn, either from water droplet or maybe a lil chem or old birdshit that was on it for too long, hard to say

I would be inclined to think that as well, but its on multiple plants and I've been careful just to water the soil at the base of the plants.

One of the necrotic spots started to turn grey and get spore like protrusions so I clipped off the dead material. I've dealt with grey mold before, but I've never seen it attack the fan leaves but not the actual buds

It's hard to understand how a healthy looking leaf suddenly gets rotten spots in it. I dont think there is a deficency. I'm thinking I might have to buy some "serenade" to prevent further spotting.

Any additional opinions are greatly appreciated.

I think its just a burn from a water droplet or nutes spilled on it, it doesn't really look like leaf spot disease unless it literally just started

Are those spots from water/nutes burning the leaves? They look similar to mine, although the spots on my plant tend to be almost completely circular. The general consensus is that these look like burns. I surely do hope you guys and girls are right. I'd hate to have some disease knock my plants out halfway through flowering.

that is the fungus. much tougher when you get it before flower. not sure but take a look at trees and grass around them. look for rusty round spots. it is bad in my area

i found an image online with a link describing "yellow leaf spot disease", like you said. It looks just like what i have... i've never heard of this before. I guess i'll have to invest in a good fungicide and hope for the best. Thanks for the help.

Definately could be leaf spot disease but I have found it spreads super quick so you should see more spots soon if not already, i wouldnt my plants with fungicide in flower unless it is for sure leaf spot disease. GL
